To all whom 2'25 may concern:

Be it known that we,

WILLIAM F. Voenn and FRANK LALANDE, citizens of the United States, and residents of Challis, in the county of Custer and vented new and State of Idaho, have inuseful Improvements in Plowshares, of which the following is a full,

clear, and exact description.

This invention relates to improvements in plowshares, an object of the invention being to provide a plowshare especially designed for cutting roots of a tough and fibrous character,

such as are commonly found in certain portions of the western United States and in other is partly of volcanic be irrigated before plowing.

localities where the soil formation and has to After soil of this character has been irrigated, the roots of alfalfa plants and other growing to cut.

plants become very tough and hard An object of this invention, therefore, as above suggested, is to provide a plow particularly adapted A further object struction, durable and comparatively inexpensive for this kind of work. is to provide a plow which will be simple and practical in coneflicient in use, and to manufacture.

With these and other objects in View, the invention consists in certain novel features of construction and rangements of parts as combinations and arwill be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings:

Figure 1 is a equipped with invention;

Figure 3 is a sectional view on the staggered line Figure 3-3 of Figure 2; and i is a view similar to Figure 2, il-

with the plowshare for cutting roots and similar obstructions.

Referring particularly to Figure 2 of the drawings, it will be seen that a toothed cutting member 5 is removably attached to the shearing or cutting edge 6 of the plowshare at a slight distance behind the plow point 7.

The member 5 is preferably curved longitudinally in accordance with the curve of the shearing edge of the plowshare.

A bolt 8 is utilized in securing the forward end of the attachment to the plowshare and the other end of the attachment 1 's removably secured to the plowshare by a bolt or other securing device 9 passed through an opening in the attachment and selectively engageable in any one of a series of plowshare.

rear end of the order to effect angular teeth 10 thereof. It is openings 10' in the This construction permits the attachment to be swung in adjustment of the to be noted that the cutting edges 11 of the teeth are located at various angles so that clogging of the teeth is unlikely to occur.

In Figure 4 of the drawings we have illustrated a slight modification, wherein the plowshare is formedwith a series of integral teeth 13 along its edge. These teeth are stantially the same ma the attachment 5, the only cutting or shearing constructed in sub nner as the teeth of difference being that they are not angularlv adjustable as in the above described embodiment of the invention.

In either instance the teeth serve to efiectively cut buried roots and the different angles of the cutting edges of the teeth prevent the clogging of obstructions on the plowshare.

Various slight changes and alterations might be made in the general form and arrangement of the parts departing from our invention,

do not wish to limit ourselves but shall consider ourselves make such slight changes and fairly fall within the spirit details set forth, at liberty to alterations as described without and hence we to the precise and scope of the appended claims.

We claim The combination with a plowshare, in-

cluding a plow point and a shearing edge, said share having a series of openings arranged transversely thereof at the end opposite said point; of a cutting attachment comprising a toothed plate extending longitudinally of said shearing edge and abutting the same throughout the length of said plate, said plate being pivoted at one end to said share adjacent the point thereof, and

means engageable With the other end of said 0 7 said shearing edge.
